Abstract

Data security at the physical layer of optical networks, or optical layer security, has received considerable research attention due to the rapid growth of optical network capacity [1]. Among various optical layer approaches, optical codedivision multiple access (OCDMA) systems are considered to be promising because of the physical encoding and decoding processes comprising these systems. Generally, physical encoding is an important concept in the field of optical layer security, which implements encoding to the transmitted optical signals, and protects the transmitted data from attack. In this paper, we provide an overview of various OCDMA systems, and discuss the impact of different physical encoding methods on OCDMA systems, in terms of security assurance. Furthermore, we introduce the application of physical encoding to optical steganography and optical transmission with wireless CDMA for security improvement.

Mable P. Fok (S’02–M’08) received the B. Eng., M.Phil., and Ph.D. degrees in electronic engineering from the Chinese University of Hong Kong (CUHK), Hong Kong, in 2002, 2004, and 2007, respectively. She was a Visiting Researcher at the University of California, Los Angeles (UCLA) and the University of California, Santa Barbara (UCSB) during 2005 and 2006, respectively, where she was engaged in research on supercontinuum generation in nonlinear fibers with the former and alloptical processing of advanced modulation format signals with the later. Currently, Mable is an associate research scholar in the Department of Electrical Engineering at Princeton University. She has published over 120 journal and conference papers. Her recent research interest is on hybrid analog/digital processing of optical signals based on neuromorphic algorithm and developing new techniques to enhance physical layer information security in optical communications network.

Paul R. Prucnal, Princeton University, Princeton, NJ, 08544, USA

Paul R. Prucnal received his A.B. from Bowdoin College, and his M.S., M.Phil. and Ph. D. from Columbia University, where he was a faculty member until 1988, when he joined Princeton as a Professor of Electrical Engineering. From 1990 to 1992, Professor Prucnal served as Founding Director of Princeton’s Center for Photonics and Optoelectronic Materials. He has also held positions as Visiting Professor at the University of Tokyo and University of Parma. Professor Prucnal is the inventor of the “Terahertz Optical Asymmetric Demultiplexer,” an ultrafast all-optical switch, and is credited with doing seminal research in the areas of all-optical networks and photonic switching, including the first demonstrations of optical code-division and optical time-division multi-access networks in the mid-1980’s. With DARPA support in the 1990’s, his group was the first to demonstrate a 100 gigabit/sec photonic packet switching node and optical multiprocessor interconnect, which was nearly one hundred times faster than any system with comparable functionality at that time. For the past several years his research has focused again on optical CDMA as well as physical layer security in optical networks. He has published over 200 journal papers and holds 17 patents. He is currently an Area Editor of the IEEE Transactions on Communications for optical networks. He was general chair of the OSA Topic Meeting on Photonics in Switching in 1999, is an IEEE Fellow, an OSA Fellow, and a recipient of the Rudolf Kingslake Medal from the SPIE. In 2005, he was the recipient of a Princeton University Engineering Council Award for Excellence in Teaching, and in 2006, the recipient of the Graduate Mentoring Award in Engineering at Princeton.
